xlock locks the X server till the user enters their password
at the keyboard. While xlock is running, all new server
connections are refused. The screen saver is disabled. The
mouse cursor is turned off. The screen is blanked and a
changing pattern is put on the screen. If a key or a mouse
button is pressed then the user is prompted for the password
of the user who started xlock.

If the correct password is typed the screen is
unlocked and the X server is restored. When typing the
password Control-U and Control-H are active as kill and
erase respectively. To return to the locked screen, click
in the small icon version of the changing pattern.

In the lower part of the password screen a text is
displayed. This message is taken from the first file of the
following that exists: $HOME/.xlocktext,
$HOME/.plan, or $HOME/.signature.

Note - if the system uses shadow passwords then xlock must be
made setuid so that it can read the shadow file. This is not
done automatically by the installation and must be done by the
administrator.

This product installs its X application default files in
/usr/freeware/lib/X11/app-defaults, which is not on the
default X search path.
There are several ways to extend your X search path. The
XUSERFILESEARCHPATH, XAPPLRESDIR,
XFILESEARCHPATH, and XENVIRONMENT
environment variables all affect resource file loading. The
easiest methods are to either create a symlink in
/usr/lib/X11/app-defaults or to add code similar to this
to your startup scripts:

(If XUSERFILESEARCHPATH is already set we append the new
directories separated by a colon, otherwise we simply set it to the
new colon-separated list. The line wrapping above is for clarity; the
actual value should be a single line with no embedded whitespace or
backslashes.)
